The cause of the constant temperature and humidity test chamber temperature difference

The structure of the constant temperature and humidity test chamber temperature among work very big harm level is well-balanced, because the structure is difficult to complete symmetry, which is bad for temperature well-balanced lead to harm. Common low temperature test chamber or constant temperature and humidity test chamber, Cold dampness aging test box) Structure. The gate in the former, central air conditioning room in the back, the wind on the next time the wind. Obvious symmetrical is good, this kind of structure can be easily done temperature symmetrical left and right, up, down, but the structure is completely different, around to work in the interior space temperature caused the asymmetrical. Even so, this kind of single duct structure such as the design scheme to solve properly, the practical experience of personal studio from 0. L ~ 300 m3, middle can be applied, the rules and regulations of the temperature error can consider. Make the box wall temperature is not symmetrical, and thus make the box wall radiation is not symmetrical, widely circulated hot harm symmetry temperature field. Because of the box wall heat conduction, heat leakage, High and low temperature test chamber) Leakage or cold ( Low temperature test chamber) Such as thermal damage, in order to compensate thermal damage is bound to appear exhaust temperature difference, high exhaust temperature of high temperature box over the operating temperature in box, exhaust temperature of the cryogenic tank is less than the operating temperature in box. Because there must be the exhaust temperature of errand work caused the temperature in the room is not symmetrical. Constant temperature and humidity test chamber work as much as possible, please don't open the door is environmental testing, open when high temperature will cause burns, for the actual operation staff to open when ultra-low temperature will meet the guy in result in cold, frozen, and will lead to air conditioning evaporator cooling effect. If must be open, please do a good job of the certain safety protection. Machinery and equipment before starting to query switch power supply is stable, wiring must be appropriate, must carry out the grounding device. No grounding device will cause accident getting an electric shock, incorrect posture safety accident and abnormal display information or accurate measurement has great deviation. In order to prevent the constant temperature and humidity test chamber to produce equipment common faults, please show me the rated current realm of switching power supply; Regular maintenance terminal screws and fixed bracket, please don't loose under the condition of the application. We should often check the constant temperature and humidity test chamber motor there is no dirt and electric conductivity, electromagnetic coils have been destroyed, the motor rotor and stator have friction, or after the motor starter motor burn down. Heater in the water to be moved around once a month, to ensure the cleaning of water, heating water dish should be clean once every month, guarantee the smooth water. Cooler should be on time every month maintenance, using wireless vacuum cleaner will be cooler heat wire adhesion of dust gettering online or use high pressure gas injection in addition to the dust. The interpretation of the above is the cause of the constant temperature and humidity test chamber temperature difference, the hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
